Sorry, had other things to work on - this one chart wasn't a priority.

Changing Security Center from Disabled to Not configured and rescanning didn't change the enviroment chart. Machines using SEP still show there as Unknown Status; even though SEP 11 and all other software and configuration info shows up in Inventory as expected.

Ah. Sorry I thought you were saying that the devices was showing up, but the AV wasn't listed in the inventory. Check your SEP and Windows firewall settings. Make sure that the system running Spiceworks can talk to the clients on the network through RDP, WMI and SNMP.

Look here for more info on scanning computers that are running firewalls:

Windows Firewal is off. RDP, SNMP and WMI, are all working. Spiceworks is properly collecting all the software and hardware information about the devices.

What's not working / inaccurate is the AV Status environment chart on the Dashboard page. Inventory page shows SEP as installed, version number, LiveUpdate installed and its version, etc. on all the 26 machines with SEP. But the AV Status pie chart shows those same 26 machines as Unknown Status - not No AV, not Out of Date, not Up to Date, etc.

I'm just going to assume that SW can't read or interpret SEP status for that chart properly; it's not that important.
